troit, in thecounty of lV-ayne and State or"- Michi 'an, hasinventedcertain new anduse tul Improvements in Jigs for Marking and DrillingFenders, of which the following-is a specification. I

This invention relates toL-a fender jig for marking and drillinglfendersin the process of construction. Automobile tenders are universally madeby a stamping operation draw the crown in a tender it is-necessary topinch the tender at the edges with what is usually called a draw ring.lThis requires the use of surplus metal that has to be trimmed oil. Thistrimming is done with an ordinary cutter and vthe work has to be guidedthrough the cutterby the worlcn'an. Hence it is necessary to properlymark the fender-s0 that the workman will be able to cut this accurately.Furthermore, the tender is drilled so the holes act as guides fortrimmingthe ends and punching the slots thru which it is attached to thewheel housmg.

It is the object of the present invention to provide a jig which willserve as amarking jig and also a drilling ji z This jig is also soformed that part of it maybe replaced to change the jig tor-similartenders without having to build an ent rely new 11g.

The female member of the is guided invertical reciprocation on the rods c and can be raised or lowered by compressed air through the instrumentality of the air cylinder and piston.The upper temale member is provided with the apron m and may be causedto descend'upon the ten- A sortot toggle clampfj the ends of the malemember for clamping the-female member in place while the mark-1 ing anddrilling operation is performed.
